Heat-treated heavy tar from the high-seed pyrolysis of Kansko-Achinsk and Mongolian (Baganursk and Tugrugnursk) lignite may be used in coking. In that case, up to 7-10% 1OSV and KS coal may also be introduced in the batch. Adding the tar improves the gross coke yield and the physicomechanical properties of the coke.
